TBS 6" 45: Kylo Ren Variant

While looking at The Black Series 6" 45: Kylo Ren figures that arrived on Walmart's Pallet displays I noticed that the color of his legs was changed from a shiny black to a flat black. My local stores had 10 of these with the Flat Black legs. The  Date Stamps were all 72281. Not sure if this is a permanent change or just a goof, since I cant find any Kylo figures around here with a newer date stamp over 72281.
